i -onshipboard and in Laying Telegraph-'Gables in a Sea or Ocean and ldo herebyv declare that the'same is fully described and represented inthe following specification and the ccompanying drawings, of Which-Figure l is a top view oi* such apparatus or, mechanism gjlFig. 2, aside elevation of it. Y

It is well known that during the process of laying a telegraplrcable inVthe ocean or on the bed thereof,'a1id from a ship-or steam-vessel Whilethe latter is in motion, there is nicre or less danger of rupture of thecable, such arising from sudden increasepf strain on it,cansed either byundue velocity or movement of the vessel. I

The object of my invention is to prevent an accident cf such nature.

In the drawingsA and B are two grooved rollersor drums, around which atelegraphv` cable, (l,A may be' supposed to be Wound or ear# ried in itspassage from the holdl to and over the stern of a vessel or ship. Eachof these drums has a set of' brakes, D D or E Eap plied to it andoperating as levers, and hinged or A,placed or jointed together', asseen-in the drawings. 'lhcse lever-brakes are borne down upon theirrespective drums by means ofsprings F 11 EF or some other suitablemethod of appl yin gpower tc them,thepressureofljhe springs on thebrakesbeing regnlatedby any suitable means, so as to produce thenecessary degree oii'ension on the cable while it is being laid.Connected with the rearinost set of springs by a crossbar, a, extendingi'ron one to the other ot' these stirrnpfhangers b, is a lever, G,turning vertically on a fulcrum at the top of a standard, ll. This leveris carried directly underneath a guide-pulley, l, and carries at itsouter end another guide-pulley or sheave,

K. Furthermore, the outer end of the lever Gr may be made elastic, as aspring, so as to spring npand down, and it may earrya Weight,

L, which I term the inertia-weight. The

cable C passes from the grooved drums to and under the guide-pulley l,and from thence to and over the guide-pulley K and into the sea. It isintended that the position of `the pulley K with respect to the pulley Ishall be such 'as shown in the drawings, or so that the cab1e,`

in passing over it, shall be bent at an obtuse angle, in order that whenanv undue strain or draft en the cable may occur such mayproduce adownward pressure on the guide-roller Ksuficient to movethe lever on itsfulcrum in a manner torelieve :the brakes from the pressure of theirsprings. Thus when the 4drums yarerelieved from the pressure of thebrakes ithev cable will run out with more free dom, and consequently notliable to be ruptured. The object of the-,spring-arm of the leer'is alsoto aid in preventing breakage of thecable during the resistance-whichresults from inertia of the working parts of the mech-` anism connectedwith the lever, ras the spring of the arm, under a sudden movement ofdraft on the cable, willy cause the arm tp yield or bend downward in amanner to prevent rupture of the cable4 prior to the elevation of -the4brakes rolnthe drums.` Furthermore, it freu quently-happcns that thestern of a sh' will rise suddenly on a sea, and in this way greatincrease of strain. on the cable may be pro@ duced. 'To prevent theinjurious e'tl'ects ot' sucha strain is the' object ot' theinertia-Weight hungon the lspring-arm of, tpe lever, the'incrtia of theWeight during the sudden rise of the ships steril being employed todepress the springar-m of the lever, V4so as to'prcvent undue strain onthe cable.

I claiui- 1.ln combination with 'a delivering-relier olQa system ofdelivering-rollers, All, a tilt- 'ing lever, G, 'o'r its equivalent, anda brake mechanism (or any. equivalent therefor) for arresting orcontrolling the revolutionsof the delivery roller or rollers, the wholebeing made to operate in such manner as to increase the paying out ordelivery'of the cable under 1n crease of tension of it1 as descrihed.

2. When the lever is applied toa brake apparatusD and ya guide-roller,K, essentially. as l describedm combining Uthe guide-rollerjwith it bymeans of al sprn g, or making theouter armf the lever as a spring, forthe purpose of en ablng such spring to operate the le'ver in manner andunder circumstances asset forth.

3. Combining' theinertia-Weight with the spring-lever, so as to causesuch'to operate as specited under a sudden upheaval of the stern of thevessel.
